I've been looking for a status syndication tool for several months now,and finally found one that looks promising. Ping.fm supports a bunch of services including the ones I care about: Facebook, LinkedIn, FriendFeed, Twitter, Pownce. In fact the one one I want that they don't support is Yahoo Messenger. But I've put in a request for that.The down side seems to be that FriendFeed ends up with duplicate entries in my feed. I think I'll have to remove the services I'm not really using so as not to annoy folks.
If you're interested in trying it out, let me know. I can give you a code that will get you into the closed beta.
I sure hope that doesn't catch on. Having tons of advertisements flooding my LinkedIn page will eventually become annoying to the point where I'll have to start pruning connections.
